This is an example of output from the show interfaces switchport command for a port configured as a
private VLAN promiscuous port. The primary VLAN 20 is mapped to secondary VLANs 25, 30 and 35:
Switch# show interface gigabitethernet0/2 switchport
Name: Gi0/2
Switchport: Enabled
Administrative Mode: private-vlan promiscuous
Operational Mode: private-vlan promiscuous
Administrative Trunking Encapsulation: negotiate
Operational Trunking Encapsulation: native
Negotiation of Trunking: Off
Access Mode VLAN: 1 (default)
Trunking Native Mode VLAN: 1 (default)
Administrative Native VLAN tagging: enabled
Administrative private-vlan host-association: none
Administrative private-vlan mapping: 20 (VLAN0020) 25 (VLAN0025) 30 (VLAN0030) 35
(VLAN0035)
Administrative private-vlan trunk native VLAN: none
Administrative private-vlan trunk Native VLAN tagging: enabled
Administrative private-vlan trunk encapsulation: dot1q
Administrative private-vlan trunk normal VLANs: none
Administrative private-vlan trunk private VLANs: none
Operational private-vlan:
20 (VLAN0020) 25 (VLAN0025)
30 (VLAN0030)
35 (VLAN0035)

This is an example of out put from the show interfaces switchport backup command when a Flex Link
interface goes down (LINK_DOWN), and VLANs preferred on this interface are moved to the peer
interface of the Flex Link pair. In this example, if interface Gi0/6 goes down, Gi0/8 carries all VLANs
of the Flex Link pair.

Switch Backup Interface Pairs:

GigabitEthernet2/0/6
Vlans Preferred on Active Interface: 1-50
Vlans Preferred on Backup Interface: 60, 100-120
This is an example of output from the show interfaces switchport backup command. In this example,
VLANs 1 to 50, 60, and 100 to 120 are configured on the switch:
Switch(config)# interface gigabitEthernet 0/6
Switch(config-if)# switchport backup interface gigabitEthernet 0/8 prefer vlan 60,100-120
When both interfaces are up, G/0/8 forwards traffic for VLANs 60, 100 to 120, and Gi0/6 will forward
traffic for VLANs 1 to 50.
